The next one is in the sequence -32
Step-by-step explanation:
Isolate x.
7
−
8
x
>
19
−
7
Add
7
to
−
7
to cancel it out because it is the lowest number here.
But you do to one side what you do to the other, so add
7
to the positive
7
on the other side. You should now have:
14
−
8
x
>
19
Now, subtract
14
from
14
to cancel it out and do the same to the other side
(
19
)
. Now, you should have:
−
8
x
>
5
Now, to isolate
x
,
divide by
−
8
.
But remember when you divide or multiply an inequality by a negative value, the sign changes around.
−
8
x
−
8
<
5
−
8
Because you divided by a negative, the sign flips:
x
<
−
5
8
Answer: Tables, graphes, and equation are realted because they all have the same information but just in diffrent ways. the advantage of a table is that you can see more information and what other possblities and fill in missing spots. graphes you can fid the equation on it by counting on it. The advantage of a equation is that you can solve it and get the answer the fastets
step-by-step explanation:
Hope this helps
2x - 4y = 32
2x - 8y = 48
2x - 2x - 4x - (-8y) = 32 - 48
4x = -16
x = -16 ÷ 4
x = -4
substitute your value of x into any of the original equations
2 (-4) - 4y = 32
-8 - 4y = 32
-4y = 32 + 8
-4y = 40
y = 40 ÷ -4
y = -10
Let's solve for b.
2b−7x=3(b−3)
Step 1: Add -3b to both sides.
2b−7x+−3b=3b−9+−3b
−b−7x=−9
Step 2: Add 7x to both sides.
−b−7x+7x=−9+7x
−b=7x−9
Step 3: Divide both sides by -1.
−b
−1
=
7x−9
−1
b=−7x+9
Answer:
b=−7x+9
